Letters Patent No. 110,320, dated December 20, 1870.

IMPROVEMENT INv HORSE-POWES.

The Schedule referred to in these Lettere Patent and making part of thesame.

To all who-m 'it may concern:

Beit known that I, JOHN \V. IVILCOX, of Macon, in the county of Bibband'in the State of Georgia', have invented a new and useful Improvementin Horse-Power; and do hereby declare that the followv such parts as Iclaim and desire to secure by Letters.

Patent.

Myinveution relates to that class of horse-powers which is used moreespecially for the purpose of operating cotton-gins, and the naturethereof consists in certain improvements in the details of thecoustruction ofthe same, by means of which the serious consequencesresulting from the sinking of the ginhouse floor, upon which part of themachinery rests, is entirelyobviated, the mechanism renderedselfadjustable, and the parts composing the machine so arranged andcombined as to facilitate convenience of operation.

In the accompanying drawing, which illustrates my invention andv forms apart ofthe specilication thereof- Figure 1 is a perspective view of myinvention, illustrating the relative position of the' various partsthereof;

Figure 2 is a plan view; and

Figure 3 is a detached View of the vertical shaft, to which the flangedpinion is secured.

The construction, operation, and relative arrangement of the componentparts of my invention are as follows:

. bolted together at the ends, as shown in the drawing, in'such a mannerthat one actsaslabrace for the other,

.The upper end of the king-post A vtits closely .within the sleeve d,cast solid with and ,upon the bottom of the internally-toothed spur-gearor kingwheel D.

The under sideof the wheel D is provided with a. flange of a width equalto the lengh of the teeth of the saidfwheel, which forms a rest for theteeth of the hanged pinion E, which is rigidly attached to the uprightshaft c. x

The main drivingwheel is provided with a gudgeon, d', the bottom ofwhich consists of a plate provided with a square point or projection,which fits into an aperture of similar shape in the core of the saidwheel, and rests `upon the` top of the kingpost. The said gudgeon issecured in position by means of bolts passing through the flange orplate` constituting the bottom thereof.l

This method of attaching. the gudgeon to the wheel causes it to assume aperfectly true and erect position, and requires less skill to ladjust itin place than would be required otherwise.

Internally-toothed spurgear is adopted as the driving-wheel, in order toinsure compactness and economy of space, and from the fact that it runswith less lfriction, and is capable of transmitting greater force thanthe ordinary spur-gears.

VThe teeth'within the driving-wheel D gear with and operate the flangedpinion E, attached to the upright shaft e. y I 4 The'said shaft passesthrough' a circular aperture out in the bed-plate-M, and is providedwith a longitudinal groove, c', for the reception of the feather-key, g,attached to the bevel-gear G.

By this arrangement of the feather-key and groove the bevcl-wheel-G isallowed to move up and down upon the shaft c, and readily adjusts itselfupon the same when the fioor to which the bed-plate is attached sinks orrises.-

The said vertical shaft e is supported in an upright and permanentposition by the flange on the bottom of the driving-wheel, upon whichthe pinion is supported, and the angeupon the pinion which rests uponthe tous of the teeth of the drivingwheel. Y

lhc bevel-wheel G engages with the bevel-gear N, attached to horizontalshaft II, which has its bearings in journal-boxes .upon thc standards I,and operates thc drum-wheel K.

The operation of the machine is apparent from prevented from settling bythe ange upon the pinion :nul the flange upon tbe bottom of tbe matinAstrueted amd operating as and for the purpose described. l

In testimony that I claim the foregoing I have hereunto set my hand this20th day of November,
